Place a large saucepan filled with water on to boil. When it comes to a boil, add the kale and spaghetti. Stir and boil 8 minutes or until spaghetti is cooked al dente.

While pasta and kale cook, heat oil in a large nonstick skillet over med-high heat. Add the sausage, onion and garlic. Saute 5 minutes, stirring once or twice. Add the pasta sauce and saute 2 more minutes.

Drain the pasta and kale and add salt and pepper to taste. Divide between two dinner plates and serve the sausage and vegetables on top. Sprinkle with Parmesan cheese.
